is it when you got it blowing on the defrost? the vents up on top of the dash blowing on the windshield? if so, i think its just the defroster clicking on.

can you pinpoint where it is clicking? Is it off of the belt or farther down?

The "defroster" is the AC compressor. Watch the front of it. The click is probably the clutch engaging and you'll see it start spinning.
